This paint marker features bold, opaque ink that writes well on a variety of surfaces including light and dark papers, cardstock, plastic, wood, glass, porcelain, and metal. Use it to decorate anything from letters and scrapbooks to glassware and home decor. It can be used with both matte and glossy paper, but shows up best on non-absorbent surfaces. It is permanent on most surfaces but not on glass or ceramic. We recommend testing the pen to make sure that it suits your purposes.
